Actually I'm interested in what games might give my new PC a run for its money - a Core i7 with a GeForce GTX 260 (running WinXP with 3GB RAM). I don't want a horror genre so Quake 4 and Doom 3 are out (and it seems from reading a couple of recent PC Gamer mags most other recent games are out too...but only the recent ones are likely to stretch this HW). I had a quick look at Diablo 2 but this hardware just ate it for breakfast. Any suggestions?

my longest straight session is probably on Fallout 3 , played it all day and then all night and then most of the morning and then went to sleep XD don't know the actual times though :/ longest iv'e spent on a game overall is oblivion. I played it on my first 360 and had 1, 100+ hour save and two 30 + hour saves , then my 360 broke [ suprise suprise ] so i gota new one and had one 40-50 hour save and now i have it on my comp and iv'e made then deleted so many saves iv'e forgotten how much they all where XD

For me the two games that I've played the most would be Final Fantasy IX and Final Fantasy XII. Last I checked on XII I had about 333 hrs on my second play. I'm not sure how many times I've played IX either.
